StackScope is a free public catalogue of indie launches. We find launches on Product Hunt, Hacker News and similar feeds, then crawl each site to detect its tech stack and score it for launch readiness: DNS, security headers, SEO basics. This page is what we saw on 21 June 2026; the live site may have changed since.
Passfile still has work before launch. Visible gaps: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.
Launched on Product Hunt on June 21, 2026. The site is hosted on Railway in the United States. The crawl picked up 3 technologies on this site, covering baas, hosting, and package cdn. The stack includes jsDelivr, Railway, and Supabase.
For context, it's on one of the most common stacks we track, shared by 269 launches.

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
